Ive been practicing making belts and attempting to dye the edges a different color than the rest of belt. No matter how precise I am it seems like the dye runs unto the back or front of the leather enough that its noticeable. Any ideas on how to keep this from happening? Should I use some kind of tape to block off the area I dont want the dye to run onto? So far my process has been: bevel the edges, dye the edges and let dry, burnish and coat with leather balm. Any help is appreciated!
